Sharp Estimates for -dimensional oscillatory integral operators with homogeneous binomial phases
Chu-hee Cho, Jin Bong Lee, Chan Woo Yang
We study oscillatory integral operators in -dimensions with a homogeneous binomial phase \[ Φ(x,y,t)=x^{k-k_P}t^{k_P}+y^{k-k_Q}t^{k_Q}, \qquad 1\le k_P<k_Q<k. \] For compact…
improving properties and maximal estimates for certain multilinear averaging operators
Chu-hee Cho, Jin Bong Lee, Kalachand Shuin
In this article we focus on estimates for two types of multilinear lacunary maximal averages over hypersurfaces with curvature conditions. Moreover, we give a different pro…
Pointwise convergence of sequential Schrödinger means
Chu-Hee Cho, Hyerim Ko, Youngwoo Koh +1
We study pointwise convergence of the fractional Schrödinger means along sequences which converge to zero. Our main result is that bounds on the maximal function $\sup_{n} |e…
Improved restriction estimate for hyperbolic surfaces in R3
Chuhee Cho, Jungjin Lee
Recently, L. Guth improved the restriction estimate for the surfaces with strictly positive Gaussian curvature in R3. In this paper we generalize his restriction estimate to the su…
